How to extract trend line data from quantmod in R

Question

Hi I'm doing a stats project for my school, but can't find a way to extract the data that is used to draw trend lines in quantmod in R

for example let's say you were to make this chart:

getSymbol(FXI)
chartSeries(FXI['2016-10-01::2017-01-10'])
addBBands()

How would I store the data points that make up the BBand?

Answer 1

Try

BBands(HLC(FXI['2016-10-01::2017-01-10']))

> tail(BBands(HLC(FXI['2016-10-01::2017-01-10'])))
